B44 steering locking

[Hog]

Right, I've searched through here but can't find what I'm looking for, so here goes.

My indoor B44 has developed a bit of slack in the inboard steering geometry. Sometimes under braking and on full lock, the steering itself will bind up sending the car the wrong way.

I'm replacing the servo horn with an alloy one as there's flex there to be got rid of. Don't want to replace all the steering parts as there's not huge amounts of play yet and the problem primarily seems to come from the Ackermann angle of the "inside" wheel under lock.

I was wondering what extending the steering arms with some carbon fibre pieces would do, so the steering rod pick up point would be further forward? Was going to make some out of an old broken shock tower - they need to be sort of ¬ shape so to avoid the diff casing.

Would this help the angle enough to stop the track rod locking?

I would replace the caster blocks and steering arms first, normally the caster block wears out where the steering arm touches on full lock.

Both were replaced recently Ben. As I mentioned it seems to be more to do with the angles involved rather than wear and tear.

I am having the same problem with my B44. I have just ordered new plastics including the complete steering setup.......hopefully this solves the problem as suggested BUT would like to hear what a few others thoughts are!
Cheers!

I know the wear in the steering assembly probably isn't helping. But I was hoping to make a workaround for this problem to stop it ever happening.

Alloy servo horns have arrived so will see what effect they have. Still looking for a suitable piece of CF to dremel into shape as well.

If you're referring to the final section of the wheel as it hits full lock, I think...this happens to all cars at full lock. It is in theory past full lock It's where the steering servo is beyond it's workable length, you could lengthen the servo horn but the wheel will foul the wishbone

I think. Well it happens on mine anyway and I've just adjusted the dual rate on the tranny
